PURPOSE OF REVIEW: To present some recent clinically relevant results from Diabetic Retinopathy Clinical Research (DRCR) Network trials that may guide management of diabetic macular edema (DME) or proliferative diabetic retinopathy (PDR). RECENT FINDINGS: Among eyes with DME and visual acuity 20/50 or worse, aflibercept, on average, had greater improvement in visual acuity over 2 years compared with bevacizumab or ranibizumab. Aflibercept is associated with higher rates of improvements in diabetic retinopathy severity among eyes with PDR and vision-impairing DME at baseline compared with bevacizumab or ranibizumab...

Importance: Variability in response to anti-vascular endothelial growth factor (VEGF) treatment in diabetic macular edema (DME) remains a significant clinical challenge. Biomarkers could help anticipate responses to anti-VEGF therapy. Objectives: To investigate aqueous humor cytokine level changes in response to intravitreal ranibizumab therapy for the management of DME, and to determine the association between baseline aqueous levels and anatomic response. Design, Setting, and Participants: In this prospective multicenter cohort study, 49 participants with diabetes mellitus complicated by center-involving DME, with a central subfield thickness of 310 μm or greater on spectral-domain optical coherence tomography (SD-OCT), were recruited from December 22, 2011, to June 13, 2013 and statistical analysis were performed from March 1, 2017, to June 1, 2017...

Plasma kallikrein, a member of the kallikrein-kinin system, catalyzes the release of the bioactive peptide bradykinin, which induces inflammation, vasodilation, vessel permeability and pain. Preclinical evidence implicates the activity of plasma kallikrein in diabetic retinopathy, which is a leading cause of visual loss in patients suffering from diabetes mellitus. Employing a technology based on phage-display combined with chemical cyclization, we have identified highly selective bicyclic peptide inhibitors with nano- and pico-molar potencies towards plasma kallikrein...

Reported here is a case of intralenticular sustained-release dexamethasone implant (Ozurdex®, Allergan, Irvine, CA, USA) present for 1 year with effective treatment of refractory diabetic macular edema without rapid cataract formation. The crystalline lens remained stable for 12 months on exam despite the presence of the steroid-secreting foreign body. The diabetic macular edema resolved on exam and on optical coherence tomography. After 1 year, cataract extraction was uneventfully performed by phacoemulsification for a mild decline in visual acuity...

Optic neuropathy (ON) is commonly complicated by microcystic macular edema (MME), that is, small vertical cystoid spaces in the inner nuclear layer (INL) of the macula. We performed a retrospective consecutive case series of 14 eyes from 11 patients with ON and MME that were treated with oral acetazolamide, acting on cellular water transport. Contralateral eyes without MME were used as controls. Segmentation of images obtained with OCT was used to determine changes of individual retinal layer thickness during treatment...

PURPOSE: To determine the association of post-operative topical prostaglandin analog (PGA) or topical beta-blocker use and the incidence of pseudophakic cystoid macular edema (CME). METHODS AND PATIENTS: This was a nested case control study. All adult patients who underwent cataract surgery between January 1, 2006 and December 31, 2016 and who were enrolled in the PharMetrics Plus database were eligible for inclusion. The association between post-operative topical PGAs (bimatoprost, latanoprost and travoprost/travoprost-z) or beta-blocker (betaxolol, levobunolol and timolol) use and the incidence of pseudophakic CME was assessed by conditional logistic regression...

Purpose: To report the case of an adult male with X-linked retinoschisis (XLRS) who presented with cystoid macular edema (CME) that responded consistently to treatment with intravitreal steroids. Observations: A 39 year old male with unilateral presentation of CME after repair of a retinal detachment secondary to XLRS responded initially to an injection of intravitreal triamcinolone acetonide (IVTA). Central subfield thickness on OCT was reduced. Three months later, the CME recurred and he was unresponsive to topical treatment so repeat IVTA was given, and the CME once again was reduced dramatically...
